Three people were detained at the Bangalore airport on Friday for questioning in connection with the recent recovery of crude explosive material onboard the Kingfisher aircraft at the airport in Thiruvananthapuram, police sources said.
All three are from Kerala, they said.
The three were about to take a flight to Dubai when emigration personnel detained them on suspicion. They were handed over to CISF, who in turn, alerted the Kerala police, which is investigating the case.
The crude explosive material was detected in the cargo hold of the flight last Sunday in Thiruvananthapuram, sparking a bomb scare.
